Folding @ Home F.A.Q.

[cadaveca]

Yep, something has to shuffle the data to the gpus...

Considering I have one HD3850 working averaging a mere 1700PPD and an overclocked QX9770 at almost 4Ghz, don't you think that 50% is a bit....extreme?

In the other thread Dashock pretty much showed that an E3110 @ 2Ghz doesn't bottleneck an 8800GT in folding. Yet here my QX9770 is working at 50% to feed info to a HD3850? It makes no sense to me.

the GPU client eats about 60% of my E8400 with the ATI card. My 8800GT averaged about 10% CPU usage. Now you know why I'm thinking about bailing on Folding@Home again.

All right, I just got off the phone with the head of ATI driver development. Thank god he answers his cell on Sundays....

I seems like the GPU v3 client will have better optimizations for ATI GPUs. The undertone of the conversation seemed to be that ATI didn't communicate their GPU layouts to the F@H GPU devs very well or something was lost in translation so even with the v2 client, things were performing the way they should.

As for me, I am switching to an Nvidia GPU the second this WU is done.

Which SMP client should I use? there is a 5.92 for Deino MPI and a 5.91 for MPICH.

You guys know you can turn down the cpu usage of the GPU2 client right?

Yes, but it negatively affects PPD it seems.

With your processor your best PPD will be with the 6.22 SMP from Folding@home - DownloadWinOther

Ah, so SMP only comes in a console version? No Systray?

Yep, that's the hole that FahMon fills. :)
